This invention relates to a water closet.

An object of the invention is to provide a water closet of the character described having a novel rtype of valve mechanism for flushing the bowl of the closet. 1 Y Y Another object of the invention is to provide, in a water closet, a ilushing valve mechanism that may be readily adjustedY to regulate the ushing period.

Another object of theinvention isV to provide, in a water closet, a` flushing valve mechanism of such construction that the parts will be readily cleansed of sediment or clogging material.

A further feature resides in the provision of a flushing Valve mechanism for a water closet of such construction as to prevent the back-ow of liquid from the bowl into the water supply pipe.

It is another object of the invention to provide a water closet having an auxiliary water reservoir provided to contain an auxiliary supply of water to insure an ample supply for flushing the bowl, either when the supply pipe furnishes a sufficient supply of water, but has low pressure, or in case the supply pipe has adequate pressure, but not sufficient Volume. This auxiliary reservoir may be located around the base of the bowl, and in the flushing valve housing formed integrally with the bowl, or may be entirely separate from the closet.

A further feature of the invention resides inV the provision of novel means for connecting the closet seat and cover therefor to the anchor post so as to relieve the hinges, for forming the connection, of excessive strain, to the end that the seat bumpers will rest firmly on the top of the bowl and the cover bumpers will rest rmly on the seat.

With the above and other objects in View, the invention has particular relation to certain novel features of construction, operation, and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein:-

Fig. 1 shows a longitudinal, sectio-nal view of the closet. ,Y

Figure 2 shows a transverse, vertical sectional View.

Fig. 3 shows a vertical sectional view of the flushing Valve mechanism.

Fig. 4 shows a horizontal sectional view taken on the line 4-4 of Fig. 3.

Fig. 5 shows a horizontal sectional View taken ,55 on the line 5 5 of Fig. 3, and

Fig. 6 shows a horizontal sectional view taken` on the line 6-6 of Fig. 3.

Referring now more particularly to the drawings wherein like numerals of reference designate similar'parts in each of the figures, the numeral I designates the water closet bowl which is of conventional construction and which is provided with the rim 2 therearound having theA channel 3 therein. n y f Leading downwardly from the channel 3 are the discharge ducts 4 through which flushing water may be discharged against the` insideof the bowl at the topi, and these ducts, if desired,

may be correspondingly inclined, or spiralled to impart a whirling motion to the water as'it is discharged into the bowl to ilush and cleanse the walls of the bowl and lessen the noise.

The bottom of the bowl is formed with a trap from whichv leads the discharge Siphon having the up-leg 5 and the down-leg 6 for the usual and customary purpose.

At vtherear of the bowl and preferably formed Y integrally therewith, there is the flush-Valve;

housing 'I which contains the flush-Valve mechanism, and which also contains a reservoir 8, for an auxiliary supplyof ushing water.

Leading from the top of the reservoir 8 into the bowl at the rear, there is a channel 9 for a purpose to be hereinafter stated.

Secured to the bottom wall of the housing I, there is a tubular anchor I0, and fitted through the upper end of this anchor, and secured thereto, there is a cylinder II. The cylinder has the outlet ports I2 within the anchor Il), and the outlet ports I3 above said anchor. A valve casing I4 is attached to the top of the cylinder I I.

The water supply pipe I 5 is connected into the valve casing I4, and the water may enter said a suitable shut-offvalve, as I8. Anchored in the valve casing I opposite the inlet openingVV lli,` there is a cylindrical cage I9 whose upper end is provided with the inlet openings 20. There is a plunger having the tubularbody 2l whose lower end is reduced in diameter to -fit within and clear the cage I 9, and whoseV lower end has the upwardly opening cup-ring 22 which fits closely within the cage. The upper end ofY the tubular body 2| has a downwardly opening cup-ring23 clamped thereon by means of the tubular gland CTI end of which is: attached the cylindrical valve 28 which ts closely in the cylinder I I. In one position, the valve 28 closes the outlet ports I2, and in another position, closes the outlet ports I3. The

upper end of the valve casing extends up through j and above the housing 1 and a closure Vcapn29M surrounds said extended upper end and forms-a close fit with the top of the housing 1 to coinpletely close the spaceV between the said valve casing and said housing.

Screwed into the upper end of the valve casing I4, there is a hood 30. containing a cylinder 3|, and screwed into thehood beneath the cylinder, there is an annular valve seat 32. `A disk valve 33grests on said seat and has a tubular stem 34 whose lower end extends down Ainto the pas- ,sageway through the gland 24, but clears the walls of said gland passageway. The upper end f of the tubular stem 34 has a transverse, key-way 35across the same through which the key 3S projects. 'Ihis key is formed on the lower end ofv the cylindrical shank 31 which extends up through a ,central opening in the hood 39 and has theV retaining nut 38 threaded thereon. On `the shankg31 there is an annular disk 39, and surrounding' the upper end ofthe stem 34, and interposed-between the Valve 33 and the disk 39, there is a coil spring 4 which normally holds the valve 33 seated againstV the seat 32. The under side of the valve 33 has the radiallyvextended channels 4I out therein, and the upper face of the seat 32 has a'channel 42 which leads out radially from the central opening 43 thereof. This'opening 43is providedfor the stem 34, and the channel 42'continues on around the upper face of theV Vvalve32, but is of a gradually decreasing capacity,

Qas'indicated bythe numeral 44 in Fig. 5. The

' margin of the valve 33 .clears the walls of the cylinder 3| and the radial channels'4l `communicate with the channel 44. The shank 31 may be readily turned by the. use of a screw driver so as'to turn'the valve 33.

lated. As.v said valve 33 is turned to'such position that ythe channels 4| will be out of communication with the channel 44 there'will be substantially no leakage past the valve 33, but if said Valve 33eis sol turned that the channels4| communicatevwith the channel 44,'the water may pass through the channels from the cylinder 3| through the opening 43 into the valve casing above the plunger. It is obvious that as the valve 33 is turned'to the left, the amount of this leak- Vage will Vincrease in accordance with the increased capacity of the channel 44 and vice versa.

Leading out from the bottom of theV anchor Ill,l and extended inwardly through the rear wall of the closet, there is the injector 45. This injec- 'tor extends through and is anchored in place by ceiving; tube 48 which, if desired,'may be formed'V i i.integrally with the closetg-itis obvious, however,4

The lower cup-ring 22 Accordingly .the amount of the water passing from the cylinder 3|, above the .valve 33,. through the channels 4|, 44, and 42, and

thence through the passageway 43 may be regu-` willY continueuntil thesupply of flushing fluid through said channels 4|, r44,*42, and thence thaty the injector and the tube 48 may be Yformed in aseparate assembly, and inserted into the bottom of the closet and suitably anchored therein. From the inner end of the tube 48, a

channel 49 leads upwardly through the wall of the bowl to the rim thereof and is connected Vby the cross-channel 59 with the channel 5I which leads downwardly Within the wall of the bowl and is preferably on the-opposite side of the bowl from thechannel 49, and this last-mentioned channel terminates beneath the bottom of Vthe-bowl in the chamber 52, and leading upwardly therefrom into the bottomv of the bowl I, are one or more jet openings 53, only one being shown.Y lThe crosschannel 50 inthe rim of the bowlis connected into ther-channel 3 which extends around said rirn. Y

Normally the bowl will be filled with water, and

' the reservoirs 8 and ad, the latter around the bottom of the bowl also will be lled with water, the

level ofthe water in the reservoirv rising tothe Y port 58, and thisy relief channel leads through the valveseat into the cylinder ll'beneath `said plunger, and the channel 51 is normally closed by the valve 55. The valve 56 is normallymain.

51 has its upper endconnected into the valve casing I4, above the plunger therein through the' J tained seated by the coil spring `59, but mayI opened by manipulatingthe handle `60, in the; usual way. When the valve 56 is opened,`the equalizing pressure against the upper end ofgthe,

plunger in the casing I4 will be at once relieved",-

and the pressure of the water entering thijpugh; the opening I6 against the cup-ring 23 will overbalance the pressure against the cup-ring 2(2,thev latter having a smaller area than the former, ,and

said plunger will be forced upwardly in the casing; ,Y

I4. The Valve 28 will accordingly move u '-e..-

wardly, also closing the-ports I3 and openingthe, portsV I2, andthe cup-ring 22 will have passed; above the ports 20 of the cylindrical cage I9 so,I that the water from the supply pipe may passv freely vdown through the cylinder `I I and through Vthe passageways )6I of the valve 28-and .out

through the ports I2, andwill pass thencethrough the injector 45 land the tube'48, passing on up.`A

through the channel 49 and into the channels 3J and 5 I; The main volume of water will pass down` Y through the channel, 5I and up through the jet opening 53 into Ythe bowl so as to start the siphon action of the water in the-bowl; -a partV of the" flushing water, however, passingaround the,

channel 3 and through the jet openings '4 'forr flushing the wallsof the bowl. The Siphon action contained in the bowl and in the reservoirs' andVV 8a has been exhausted. IfY the pressure and..

' Ywithout that contained in the reserve reservoirs 8 and 8a, but if the pressure is low, or Ythe volume inadequate, 'the reserve water in said ,reserve reservoirs will be exhausted, or partially exhausted f to give an adequate flush of theY bowl. e

When the ilushing operation started, `the lever 60 is releasedand the valve 56 immediately closed and water Vwill begin to accumulate inthe begin tok descend. "Upon descent of thenplunger,

" casing I4 above the plunger and said plunger will Y 'the ports I2 closed and the ilushing huid thus cut oile from the injector'45. The descentI of the valve 28 will be gradual so that some of the openings I3 are uncovered before the cup-ring 23 has passed beneath the lower ports 20 so that the water may continue to flow in through theV -supply pipe and opening I6, and ports 20, and thence through the cylinder II and out through the ports I3 to ll the reserve reservoirs 8 and 8a before the plunger reaches the limit of its downward movement so as to close the ports I2 and to cut olf the flow of the inflowing water from the cylinder II and the ports I3.

The rapidity with which the wateraccumulates in the casing I4 above the plunger, and consequently the rapidity of the descent ofthe plunger,

will be controlled by the adjustmentA ofthe valve -The length of time required for the flushing operation will accordingly be determined by the adjustment of this last-mentioned valve.

' Ashereinabove indicated, water which accumulates Yin the casing I4 above the plunger ows in through the screen, or screens, 26, and up around the tubular stem 34, as well as up through it. As the plunger moves up and down, any sediment that might tend to collect between the stem 34 and the plunger will be removed. When the plunger reaches the end of its upward movement, the head 26 will strike the lower end of the stem 34 and suddenly lift the valve 33 permitting the water, under pressure, in the cylinder 3l to flush in ,between the valve 33, and its seat to keep the same washed clean.

Connected into the valve casing I4, there is an upstanding rell tube 62 whose upper end 'B3 is overturned and directed toward the upper end of the overflow channel 9. During the flushing operation, with the plunger elevated in the casing I4, the inflowing water may also be dischargedV Water in the supply system should fail, creating a' vacuum in said system, the tube 62 acts as an air-supply tube so as to prevent back-siphonage of the water from the bowl into the supply system,

thus avoiding pollution of the water in the supplyVY system. f

'Ihe numeral 64 designates the closet seat, and the numeral 65 designates the seat cover. The toilet seat is equipped with the legs 66 arranged to rest on the top of the rim 2 and the cover is provided with the legs 61 arranged to rest on the seat 64. Anchored to the forward side of the housing I at the top are the anchor posts 68, 68, which support the transverse rod 69. Pivotally mounted on this rod are the links 10, 1I, whose forward ends are pivotally connected toy the seat and cover respectively. 'Ihis arrangement provides a ilexible connection for the seat and cover so that they will readily assume position'to permit the legs 66 to rest rmly on the rim 2, and to permit the leg 61 to rest rmly on the seat 64 without undue strain on the hinged connection Y clogged and the water should rise therein, andV overflow, the rim 2, the polluted water from the bowl can not enter the overflow channel 9 and pass thence into the reservoir 8. This trap 'I2 also provides an air-inlet so that in case the closet is flushed while it is so clogged' and-'overflowing air will Vbe permitted to enter the reserve chamber 8 to prevent the formationv of a vacuum therein. l
